Acclimation Period

[sneaky_boa]

I probably should have put this in a more specific forum...but I'm so concerned I need as many expert opinions as possible.

Just received a hatchling redfoot shipped from Vancouver on Thursday. First night, tort was fairly active, exploring and ate a little. Since then it has been in its hide area and has not emerged for food or water. Husbandry is perfect (day temp 85-90; night temp 80, humidity 70%). At what point do I become very concerned about the lack of food consumtion, and what do I do then? How long an acclimation period is normal???

Thank you all!!!
